SPECIFICATION forming part of Letters Patent No. 374,763, dated December 13,1887.

Applicationfiled October 26, 1887. Serial No. 253,391. (No model.)

T 0 all whom, it Hwy concern;

Be it known that I, JOSEPH TocrN, a citizen of the United States, residing in Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Car-Couplings, of which the following is a specication.

My invention relates to certain improvements in automatic car-couplings, whereby either passenger or freight cars may be easily coupled together or a freight and passenger car may be readily coupled together or uncoupled without danger to life or limb, and when conditions render it arbitrary an ordinary link and pinl may be used in coupling either freight or passenger cars together, all of which will be fully and clearly hereinafter described and claimed, reference being had to the accompanying drawings, in which.-

Figure 1 is a side elevation of theinvention, showing a portion of two cars-a freight and passenger car-coupled together. Fig. 2is an enlarged detached plan or top view of the coupling, showing the twg portions coupled together. Fig. 3 is a longitudinal section through a car-platform, crosslbeanis, and caraXlcs in line a b, Fig. 4, showing a side elevation of the cou-pling device complete. Fig. 4 is a bottom view of a car and the coupling mechanism connected thereto, showing a bottom lview of the invention. Fig. 5 is an end view ofa freight-car, showing a front end view of the coupling and the position of the parts when the coupling is closed. Fig. 6 is an end view of a platform car, showing the coupling when attached thereto and the position of its parts when open. Fig. 7 is an enlarged crosssection through line c d, Fig. 2, all the partsbeyond the coupling-case and its bottom supporting-plate being omitted. Fig. 8 represents a crosssection on line ef, Fig. 2, cutting through the coupling-supporting plate and coupling-slides, all partsV beyond it being omitted.

I have shown a portion of a car and cartruck in connection with my invention, bccause it is impossible to show and describe it clearly without them, as a portion of the coup'- ling is attached to and forms a part of the truck, and a portion of the coupling is also attached to and forms part of the car.

The coupling-supporting plate 1 is made of cast-iron, or preferably caststeel, and is rigidly secured by bolts 2 (see Figs. 2, 4) to the lower cross-beam, 3, of the truck. wheels 4, shafts 5, braces 6 6a, and cross-pieces (The caror beams 37 are made in usual way.) The Y cured, by bolts 12 13, a casing or cover, 14, (see 6 A Figs. 1, 2, 3, 7,) into which the buffer is tted so as to slide longitudinally back and forth. It is provided on the inside with a rib, 15, at the top, and directly opposite the rib 15, on the bottom, is a similar rib, 16. (Shown in Fig. 7.)

The buffer is fitted so as to slide easily in the. case 14, and is kept in place in said case by the ribs 15 and 16. (Shown in Fig. 7.) The buffer-head 18 is of the usual form, except the side 19, which is madefheavier and to incline to one side, as shown, so as to provide a face to receive the holding-hook. At the rear end of the buffer isa strong spiral spring, 20, se# cured thereto by a bolt, 21. (See Figs.- 2, 3.) This spring 20 is kept in place by plates 22, adapted to slide on the slideways 23. (See Figs. 3, 8.) The slideways 23 are rigidly secured to the upright pieces 24, and the parts 24 are bolted, by bolts 25, to the supportingplate 1. (See Fig. 3.)

On one side of the buffer 17 is a projecting piece, 26, (see Fig. 2,) through which passes a bar, 27. (Shown by dotted lines in saidFig. 2.) On the forward end of the bar 27 is pivoted, by a pin, 28, a holding or coupling hook, 29, which passes through the case or cover 14 between the ribs 15 16 (see Fig. 7) and through the yoke 30, which is attached to Y or forms a part of the buffer. vA spring, 31, within said yoke, (shown in Fig. 2,) at the back ofthe holding-hook 29, keeps it forward at all times in the proper position for keeping the coupling f closed.

At the rear portion of the bar 27 is a rubber spring, 32, (also shown in Fig. 2,) and at the end is a washer, 33, and a nut, 34, for keeping said bar 27 and the spring in their proper positions. f

ICO

On the pin 34 is rigidly secured, by means of a set-screw, 35, (shown by dotted lines, Figs. 2, 4,) or in any well-known way, a bar, 36, having curved sides and rounded ends.- It is placed between the upper and lower sides of the buffer, and on the lower side ofthe pin 34 is rigidly secured in or about in aline with the length of the bar 36 an arm or lever, 37. It will be seen from this construction that by turning the arm 37 into the position shown by the dotted lines hin Figs. 2, 4 the coupling will be opened on both cars, (where two are coupled together,) or only one when operating with a single car, as in Fig. 4, the couplinghooks 29 being opened out by this operation, as shown by the dotted lines g in Figs. 2, 4. In using the coupling on a platform car, as shown in Fig. 6, the arm or lever 37 may be used alone, as shown in said Fig. 6.

Just above the arm 37 is a curved plate, 38, rigidly secured to the buil'er, or in one piece with it. On the underside of this curved plate are two notches, 39 40, into which the arm 37 springs when turned to the limit of its motion either way. (See Figs. 3, 4.)

On passenger or freight cars such as shown in Figs. 1, 3, 4, 5 the arm 37 is provided with an upwardly-projecting pin, 41, and to the car is secured a vertical rod, 42, so as to be capable of a vertical movement up and down, and is held down by a spiral spring, 43. (See Figs. 1, 3, 5.)

At the foot of the vertical rod 42 is rigidly secured a slotted arm, 44. This arm 44 is bent so as to bring the slotted portion down to meet the upwardly-projecting horizontal portion of the arm 37, so that the pin 41 can project up through the slot 45 in the arm 44. The top of the rod 42 is provided with an operating-handle, 46.l This handle is preferably placed as shown in Fig. 5, because it is out of the way when the couplings are closed or the cars coupled together; but, if desired, they can be placed as shown in Fig. l. By this construction the cars are coupled automatically by running them' together, and they may be uncoupled by turning the handle 46 so as to move the arm 44 into the position shown by the dotted lines in Fig. 4, thereby bringing the arm 37 into the position shown by the dotted lines h, and then by turning the handle back into its normal position the cars may be coupled automatically, as above mentioned.

The object of the spiral spring 43 isto allow for the movement of the car as it moves or springs np or down, `the projecting pin 4l moving in the slot 45 as the car rises or falls.

Freight-cars may also be unconpled from the outside, when required, without danger of accident, by taking hold of handle end 47 of the arm 37. cars the handle portion 47 is not required. (See Figs. 2, 3', 4.) To hold everything strong and rigid I secure a brace, 49, by the center pin, 50, of the truck, and tothe bottom of the car by bolts 5l. (See Figs. 3, 4.) This is necessary, because the coupling is attached to the truck and forms a part of it, and by this construction the coupling turns with the trucks while rounding curves, Vso that the several parts do not become cramped or strained. If at any time it becomes necessary, a common link and pin, 52 53, may be used, as shown in Fig. 4.

I claim as my invention-- 1. The combination of the brake-rod 42, having an operating-handle at the top and a slotted arm at its lower end, a spring for holding them downward, an arm having a pin which projects up through the slot 45 and having its end connected rigidly to a pin, 34, provided with a short uncoupling bar, 36, rmly secured to it, and a coupling-hook pivoted to the buffer and kept in its normal position by a spring, 31, as and for the purposes described.

2. In a car-coupling, the combination of a supporting-plate secured to the cross-beam of a car-truck by bolts and flanges, a brace, 49, secured to the truck and car for rigidly supporting the coupling, a buffer-case secured by bolts to the supporting-plate, a buffer having a spring secured in slideways at the rear and a buffer-headV provided with a face having an inclined back portion on one side, acouplinghook pivoted to thv opposite side and kept in its normal position by a spring. and an arm provided with a bar, 36, pivoted to the buer, substantially as and for the purposes described.

3. The combination of the brake-rod 42, having an operating-handle, aslotted arm rigidly secured to its lower end, and a spiral spring interposed between the car and the slotted arm, and an arm pivoted to'the buier and carrying an uncoupling-bar, and a pin, 41, rigidly secured to the arm and projecting np through theslot 45, for the purpose of allowing for the vertical springing or other movement of the car, substantially as described.
